You just need to 'del sheets' once after the loop, no need to do it in
every iteration. After your original loop the 'sheets' variable still
pointed to the last sheet object, probably causing it not to be
properly cleaned up. This is the only thing that your change fixes,
but it is simpler (and more readable) to just do it once after the
loop.

(Please add SOLVED or FIXED to the subject when your issue has been
resolved, so that people like me don't read the whole thread only to
find that their help is no longer needed.)
